[Shop-talk] Heating question (not so much shop related.)

[Pat Horne]

My gut reaction is that it is slightly more efficient to run the system as you are. Hot air rises, so the downstairs unit heats the upstairs enough for your tastes.  If you run the upstairs unit, it won’t keep the downstairs heat from coming up, so the upstairs unit probably won’t run much, only the short time when the upstairs temperature is low, which won’t be often. 

A related question is whether not running the upstairs unit is causing any long term damage to itself by not running. 

Peace,

OK, this is more of a thought experiment, but here is the back story.   

My house is over 200 years old.  2 years ago I got  vinyl siding and better insulation.  REALLY good insulation. 
I have programmable thermostats (2 zones, downstairs and upstairs.) 
I keep them at about 64 degrees when I'm there. 
Turns out, the batteries in the upstairs one went dead and my upstairs zone hasn't turned on in over a year. 
HOWEVER, I really like how the house is.  The downstairs is as warm as I want, and the upstairs is just slightly cooler, but it's perfect for sleeping. 

My question is, is it more efficient to have the upstairs not run heat?  Or is the downstairs working much harder to compensate? 

I know there are lots of variables, but what do you guys think? 

Thanks!
